The film takes place in the 1920s and stars Nicole Kidman as Lili Elbe, nee Einar Wegener, a Danish artist who falls in love with fellow artist Gerda Wegener, to be played Paltrow.

The story of Wegener's transformation begins in the fictionalized novel by David Ebrshoff with him donning "stockings and high-heeled shoes, perhaps even a dress, just for a little while, so (his wife, Greta) can finish the bottom half of a woman's portrait," according to The New York Times.

Hallström and Kidman have both shown flashes of greatness throughout their careers and it's easy to understand why being married to Paltrow could make you want to become a woman.
